Title: Controller for speed of wound-rotor induction motor
Inventor: KUGE KATSUTAROU
IPC: H02P25/026
Filed: 1980-04-25
Abstract: PURPOSE:To hold a power-factor in an ideal value by controlling the amount of power at the secondary side of a motor returned to a power source by difference between reactive power at the primary side and reactive power set and signals obtained by adding secondary current signals to difference signals between actual speed and set speed. CONSTITUTION:Reference reactive power is given by a resistor 25, and controls a converter 3 at the secondary side of a motor 1 through a computing element 28 and a phase control circuit 30 together with reactive power signals from a reactive power detecting circuit 10 at the primary side. Reference speed is given by a resistor 15, inputted to a computing element 18 together with actual speed and changed into reference torque, actual torque signals from a torque detecting circuit 14 are further added and an inverter 4 is controlled through a phase control circuit 24. Thus, since a minor loop of speed control is controlled by torque, the variation of a main circuit due to the control of a power-factor has no effect on speed control, reactive power at the power source side is freely controlled and an ideal power-factor can be obtained.

Title: Switching regulator
Inventor: SHIMODA SADAYUKI
IPC: H02J1/00
Filed: 1995-03-15
Abstract: PURPOSE: To prolong the service life of a portable apparatus by providing means for switching the substrate potential of an MOS transistor between the coil side and the output terminal side in parallel with the MOS transistor thereby preventing the power supply voltage from appearing at the output terminal upon interruption of voltage step-up operation. CONSTITUTION: At the time of voltage step-up operation, the substrate potential of an MOS transistor is equalized to the potential at an output terminal 6. Consequently, the parasitic diode of the MOS transistor is formed such that the anode and cathode thereof are connected, respectively, with the other end of a coil 2 and the output terminal 6 at the time of voltage step-up operation whereas the anode and cathode of the parasitic diode are connected, respectively, with the output terminal 6 and the other end of the coil 2 upon interruption of voltage step-up operation. Since the MOS transistor is not conducting when the voltage step-up operation is interrupted and the parasitic diode of the MOS transistor is formed in reverse direction from a power supply 1 toward the output terminal 6, voltage of the power supply 1 does not appear at the output terminal 6.

Title: Carburetor with variable venturi tube
Inventor: INOUE TADAHIRO
IPC: F02M7/17
Filed: 1979-05-10
Abstract: PURPOSE: To prevent adhesion of fuel to a throttle valve and reduce the overall height of a variable Venturi tube type carburetor, by making a suction piston slanted at the lower portion close to which a throttle valve is positioned.  
     CONSTITUTION: A suction piston 17, which is driven by negative suction pressure introduced through a negative pressure intake hole 37, is positioned horizontally in a vertical suction passage 41. A needle 28 to be moved back and forth in an orifice 29 is fixed at the tip of the piston 17 for adjusting fuel feed. At the lower portion of the piston 17 is formed a slant surface 36 close to which is positioned a throttle valve 38. Since fuel discharge through the orifice 29 flows in the suction passage 41 from an opening of the throttle valve 38, little fuel adheres to the throttle valve 38.

Title: Detecting method of change in physical quantity
Inventor: KUSUSE TAKASHI
IPC: G01D1/10
Filed: 1988-03-10
Abstract: PURPOSE:To perform operation judgement for only a predetermined change of physical quantity, without responding to a momentary change thereof, by judging the direction of change of every sampling data within a predetermined period thereby to perform the operation judgement only when said change is repeated a predetermined number of times in a fixed direction. CONSTITUTION:A row of samplings 3 is formed in accordance with the change of a system voltage 2. A condition that data V3-V9=DELTAV>=DELTAV5 is established at the 9th sampling, and an operation judgement 4 indicates 'operation'. In this case, the number of judgements 5 in the direction of the change within a predetermined period DELTAT between the data V3 and V9 is 6, and 'fall' is judged four times among the six. If a reference for the direction judgement 5 is so decided as to judge 'fall' when 'fall' is observed four times or more among the six judgements, when the two conditions, namely, the operation judgement 4 and 'fall' judgement are met, a final operation judgement 6 is made as 'operation'.

Title: Adapter with humidity sensor function
Inventor: KAWAGUCHI TOSHIYUKI
IPC: G02B6/00
Filed: 1989-03-09
Abstract: PURPOSE:To provide the lightweight and small-sized optical adapter which can immediately detect the infiltration of water in the juncture of optical fiber when such infiltration arises by mounting a humidity sensitive permeable material between the end faces of the right and left optical fibers which are supported in adapter bodies and are butt-connected. CONSTITUTION:The humidity sensitive permeable material 14 is mounted between the end faces of the right and left optical fibers 7 which are supported in a butt state in a pair of the right and left adapter bodies 1. The material 14 is formed by applying a material which causes a change in the transmission factor of light with an increase in humidity, for example, cobalt chloride, etc., on one or both surfaces of a transparent plate such as, for example, quartz glass plate. The attenuation of light between the optical fibers 7 and 7 hardly arises unless the cobalt chloride, etc., are discolored by moisture. If, however, the water infilters in this part, the moisture arrives at the surface of the material 14 through a communicating hole 15 formed in the adapter bodies 1 and causes a change in the transmittance of light and, therefore, the infiltration of the moisture is known from the attenuation factor of the light between the optical fibers 7 and 7.

IPC: B21B39/08
Filed: 1982-04-07
Abstract: PURPOSE:To correct widthwise staggering of a plate by giving separated bridle rolls a speed difference when a position detector detects the plate staggering. CONSTITUTION:When a plate conveying unit is operated in such a way that, when the tension from separated rolls 2A and 2B to steel plate 4 is in same conditions widthwise, if, for example, the steel plate 4 staggers toward the left side, viewing from the rear, the tension that is given to the steel plate 4 from the lefthand roll 2B of the separated rolls is decreased so that the steel plate 4 is pulled toward the right side, viewing from the rear, and the staggering is eliminated. A position detector 5A that detects the widthwise position of a steel plate is installed at the rear of bridle roll. The detector detects the amount of staggering of the steel plate 4 and feeds back these outputs to the tension standard of driving motors 3A and 3B for each separated roll so that plate staggering can be automatically corrected all the time.

Filed: 1988-03-10
Abstract: PURPOSE:To enable clear printing to be performed on rough paper even though a heating amount of a heating part and pressure force to recording paper are not so elevated by using a resin ink ribbon, by a method wherein a glaze layer is formed in contact with an edge part of a substrate, a heating part is formed on this glaze layer and besides, a signal electrode and a common electrode are led out in the same direction. CONSTITUTION:A partial glaze layer 2 of an almost arc state in a section is formed in contact with an edge part of a substrate 1, and a heating element 3 is formed on the partial glaze layer 2. Then, a common electrode 4 is formed on the partial glaze layer 2 and in contact with the heating element 3. A signal electrode 5 is derived from two heating elements 3 adjacent thereto in the same direction as that of the common electrode 4. Further, a collecting electrode 6 connects the common electrode 4, to be led out to another edge of the substrate 1. Then, a space between the signal electrode 5 and the collecting electrode 6 is insulated by a layer insulation material 7. Thereby, clear printing can be performed on even rough paper and besides, dispersion of a resistant value to the heating element 3 observed from the collecting electrode 6 can be easily reduced to a range capable of being neglected by optionally adjusting a width of the collecting electrode 6.
